Re: What year and HP is this carburetor 322276? Can't find part number anywhere
You don't indicate whether this is a V4, V6 or a 3 cyl engine. Your jet size is perhaps a mid-jet size. I'd do a couple of things 1. determine the configuration of the bowl first. Some bowls have only a single screw on each side, hiding the main jet. Some have two screws on the side, each hiding jets. Some have a single side screw and a mid-jet inside the bowl-only accessible by bowl removal. Each type of bowl refers to a different age/year group. 2. Once you identify the age range, then start of compare the main jet size. They are unique to hp and to year. Many differed every year, so they become a unique trait. 3. It is unusual to have different jets in same carb positions in the same engine, but not unheard of. Some engines (a few) used different jets in the same carbs to control the cyl firing temps. Esp on those V6 engines with the 25" midsections.
